Rather than go to the trouble of moving house and packing up/transporting everything which would take me and my partner months even with hired professional movers I usually opt to buy another vacant block in the vicinity, erect a sealed/lined warehouse sized shed with security system and store any overflow there in the interim rotating them in and out on an as needs basis.
Most of the fresh container imports, ongoing restoration projects and machines for immediate sale are at that location so it works well as you don't have the inconvenience of randoms showing up at your main residence. Whilst at the same time you keep the finished restored products in the main residence gamesroom for regular play.
I use this same method/rationale for a bulk of my car collection as well. The lesser valued vehicles get stored offsite in one of the secure sheds, the Ferrari and other high value models stay close to home base for obvious reasons. More practical for insurance purposes as well.
